rtems_bsdnet_ifconfig problem using C++

[Aitor.Viana.Sanchez at esa.int]

Hi all,

I got some problems with the network configuration when using C++. 

In the main.cpp source code I include:

#include <rtems.h>
#include <bsp.h>
#include "../rtems/rtems_config.h"

extern "C"
{
        #include <rtems/rtems_bsdnet.h>
}
#include "../rtems/rtems-network.h"

#include <rtems/rtems_bsdnet.h> is include within the extern statement 
because otherwise i cannot use the rtems_bsdnet_initialize_network() 
method. The rtems-network.h is the network configuration file (pretty 
similar to the one provided with the RTEMS examples) and also is working 
perfectly with previous C projects.
The problem is that when I try to compile the application i get the next 
error:

/home/aitor/workspace/OBSFramework/src/rtems/rtems-network.h:97: invalid 
   conversion from `int (*)(rtems_bsdnet_ifconfig*)' to `int 
   (*)(rtems_bsdnet_ifconfig*, int)'


where the line referenced in the error is the next one

static struct rtems_bsdnet_ifconfig netdriver_config = {
        RTEMS_BSP_NETWORK_DRIVER_NAME,          /* name */
        RTEMS_BSP_NETWORK_DRIVER_ATTACH,        /* attach function */

#ifdef RTEMS_USE_LOOPBACK 
        &loopback_config,               /* link to next interface */
#else
        NULL,                           /* No more interfaces */
#endif

#if (defined (RTEMS_USE_BOOTP))
        NULL,                           /* BOOTP supplies IP address */
        NULL,                           /* BOOTP supplies IP net mask */
#else
        "192.168.1.29",         /* IP address */
        "255.255.255.0",                /* IP net mask */
#endif /* !RTEMS_USE_BOOTP */

#if (defined (RTEMS_SET_ETHERNET_ADDRESS))
        ethernet_address,               /* Ethernet hardware address */
#else
        NULL,                           /* Driver supplies hardware 
address */
#endif
        0                               /* Use default driver parameters 
*/
};

I don't know why this is happening. Can anyone give a clue?

Thanks in advance,

Aitor

Depends on the version.  For 4.7 and older, the routine
you want is _TOD_To_seconds() from the SuperCore.

For 4.8 and newer, it has the same name but is part
of the RTEMS Classic API since the SuperCore doesn't
know the Classic API TOD structure any more.

libbsp/shared/tod.c has an example of using it.

In 4.8 and newer, there is also a set of timespec math
routines prototyped in score/include/rtems/score/timespec.h
